Hydrothermal Synthesis and Characterization of a Novel One-Dimensional Titanium Glycolate Complex Single Crystal: Ti(OCH₂CH₂O)₂

Abstract

Single crystals of a novel titanium glycolate complex, Ti(OCH2CH2O)2, have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, thermal analysis (TG-DTA), and scanning electron microscopy (SEM). The titanium glycolate complex crystallizes in the monoclinic space group C2/c (no. 15), with unit cell parameters of a = 15.204(9) Å, b = 7.568(2) Å, c = 5.816(6) Å, β = 110.87(6)°, Z = 4, R = 0.036, and Rw = 0.033 for 598 reflections (I > 3σ(I)) and 43 variables. The structure is described as parallel chains built up from edge-sharing Ti4+O6 octahedra. The six oxygen atoms are offered by four ethylene glycolate ligands. Each ethylene glycolate ligand bridges two titanium atoms with one of its oxygen atoms, and the other is terminal.
